HELP! Need car camping spot for 2nd w/end. Willing to split costs.

Im an Australian Coachella first-timer looking for a car camping spot with my girlfriend who is from LA. We are going separately with friends who are staying in hotels but both wanted the whole camping experience. I am 30 and she is mid-twenties, we both love a party but also love our sleep AND our live music. Am willing to split the costs of the site.
